LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 311,576, dated February 3, 1885.

Application filed December 9, 1884.

T0 aZZ whom it may concern:

Be it known that I, ISAIE FREOHETTE, of

the city of St. Hyacinthe, county of St. Hyacinthe, Province of Quebec, Canada, engineer, have invented new and useful Improvements in Lubrioators; and I do hereby declare that the following is a full, clear, and exact description of the same.

This invention has reference to an improved construction oflubricators in which an endless chain is used, placed upon the shaft close beside the journal to be lubricated, the lower end of the said chain being immersed in oil, 810. As the shaft revolves the chain travels with it and drawsup a body of oil, 830., which is in part thereby placed on the shaft beside the journal and by capillary attraction is drawn into the hearing; but when the shaft is provided with collars next to the journal the chain cannot be laid close up to the journal unless it is laid upon the collar, and if thisis done the centrifugal force of the revolving collar and shaft militate against the capillary attraction and prevent it more or less from drawing the oil, &c., into the bearing. If the shaft is one revolving at the high speed so common in use, there is no doubt that the oil, 8m, will be altogether prevented by the centrifugal force from entering.

The object of my invention is to overcome this difficulty and cause the bearing and jour nal to have full lubrication under all speeds of revolution. proveinents, which will be hereinafter set forth and claimed, are the objects of my present invention or improvements.

In the drawings hereunto annexed, similar letters of reference indicate like parts, and Figure 1 is a side elevation of a bearing and shaft, 820., embodying my invention. Fig. '2 is an end sectional elevation of the said embodiment shown in Fig. 1. Fig. 3 is aplan of the upper'half of Fig. 1. Fig. 4 is a transverse section on line as 00, Figs. 5 and 6. As the sections in these two figures are exactly alike, Fig. 4 will truly represent both. Figs. 5 and 6 are longitudinal vertical central sections on line 00 m, Fig. 3, the one being a slight modification of the other. Fig. 7 is an elevation of the lower wheel and longitudinal section of oil-tank. Fig. 8 is alongitudinal or front see- This, together with other im- (No model.

tional elevation, showing my in'i p ro vcments as applied to a loose pulley on a shaft. Fig. 9 is a vertical longitudinal section of the parts shown in Fig. 8. Fig. 10 is a transverse elevational section on line a; 00, Fig. 8.

Letter A is a shaft having collars B, theportion of the shaft lying between the collars be ing received within a plumber-block, hanger. or other bearing, of which 0 is the upper and D the lower parts. These two parts are at tached together by bolts in the ordinary way, or as shown.

In the end of the part of' the bearing 0 a semicircular passage or recess, E, is formed, adjoining the shaft and collar, as shown in Figs. 4 and 5. This passage is extended through the lower part, D, of the hearing by forming passages F in it, the whole being covered by one of the collars B, as shown in Figs. 2 and 5.

As shown in Fig. 6, the passage E may, if desired, be situated at a distance from the end of the bearing, and passages F formed. in the lower part of the bearin g to correspond with it.

In the above-described passages E and F an endless chain, G, will be placed, the lower part of which will reach down into the oil,&c., in the tank H. This tank has upward projections L by means of which it is attached to the bearing, and these projections I also form dash-guards to prevent the chain from distributing the lubricating material round about the location of the bearing, which is a very necessary precaution when a high'speed of revolution is used.

As a further improvement, I provide a grooved wheel, K, in the tank H for the lower part of the chain G to run upon. This wheel need not tighten the chain, but will be set at such a distance as to prevent the vibrations from causing kinks in it.

I am aware that hooks have been used before for this purpose; but they are more calculated to retard the free action of the chain than to catch upon the hook. The impor Here sis in every respect of ordinary construction.

The pulley O is, however, provided with an extended sleeve, D, in which is formed a groove, E, for the chain G to run in, also to reduce the centrifugal force. It is therefore made as deep as the required strength of the parts will permit. The part F of the sleeve reduced by forming the groove E is provided with a number of very small perforations, G, radial to the center of the shaft A, and oblique perforations H; All these perforations are made small, so that their capillary attraction may be great, and thoseH' being oblique will draw in the lubricating material when the radial ones fail, on account of the centrifugal forceof revolution overcoming the capillaryattraction.

Therefore it will be seen that the perforations G may, if desired, be dispensed with in pulleys revolving at very high speeds.

WVhat I claim, and wish to secure by Letters Patent, is as follows:

1. The combination of the shaft A, having collars B, bearing 0 D, having passages E F, as described, chain G, and tank H,with a fluid lubricating material, the whole constructed and arranged substantially as shown and described, forthe purpose set forth.

2. The combination of the shaft A, having collars B, bearing 0 D, having passages E F, as described, chain G, tank H, and grooved wheel K, with a fluid lubricating material, the whole constructed and arranged substantially as shown and described.

3. The combination of the shaft A, having collars B, loose pulley 0, having extended sleeve D, provided with groove E, and perforations, as described, with chain G, and tank H, the whole constructed and arranged as described, substantially as shown and described.
